I don't use CubeMX - I write to all the SPI registers directly.STM32F030C8I have SPI1->CR2->DS set as 7 (8 bit data transmit) but the CPU is transmitting 16 bits for each write to the SPI1->DR register.I verify this using a logic analyzer.I can't fin...
Hi,I am using the stm32L100RBT6 and I have successfully implemented the stop mode.I have chosen to wake up the µC from stop mode either by RTC or by an external interrupt.Before I put the µC in stop mode, I set all the pins to analog to save power an...

Hi,we have a problem with low power application developed on STM32L452RE with BLE BlueNRG-M2SA module to read environmental sensors (STTS751, HTS221 and LPS25)The application is developed on the STM32CubeIDE (1.5.1)At the start of main code the IWDG_...
I'm somewhat new to scatter files and I'm trying to understand them better by doing some tests on a ST32F765 project (with 2mb flash at 0x0800 0000 - 0x081F FFFF).This scatter file works OK:LR_IROM2 0x08100000 0x00100000 { ; load region size_regi...
rxBuf is uint8_t array. // this creats HardFault sometimes: id = *(uint32_t *)&rxBuf[i]; //---------------------------------------------------- // but this works OK forever: id = rxBuf[i + 3]; id <<= 8; id += rxBuf[i + ...
What happened to the equivalent of I2S_FLAG_CHSIDE as I don't seem to be able to find it.Or do you just count the interrupts and assume it goes Left - Right - Left... forever?ThanksAndy.
Where can I find the default values for the option bytes? I'm using a STM32L151CCI mean the option byte values stored in the factory on delivery.
Hi,I recently need to use I2C with interrupt mode to lower my CPU usage.So I did this changes :I changed the function where I call my transmitstatic HAL_StatusTypeDef PGA309_Write_RawData(uint8_t REGISTER,uint8_t LSB_DATA,uint8_t MSB_DATA) { uint16_...
